We are happy to announce that Hudiy 1.16/2.12 is now available. You can find the release highlights below:

Direct renderer

In version 2.8, we introduced the direct renderer, which is optimized specifically for CarPlay and Android Auto video streams. Initially, it was designed for console mode on lower-end Raspberry Pi models (Pi Zero 2, Pi 3B, and Pi 3B+). In current release, we successfully ported the direct renderer to the Raspberry Pi 4B, Raspberry Pi 5 and x86_64 with VAAPI support.

Thanks to the direct renderer, video playback is more efficient and smoother due to tailored optimizations for CarPlay and Android Auto.

Starting with this release, the direct renderer is the default for Raspberry Pi in both desktop and console modes. The composition renderer will still be available and you can easily switch between them using the HUDIY_RENDERER environment variable.

Due to hardware diversity (GPU, VPU) on x86_64, the composition renderer remains the default on this platform since it is more universal. However, if your x86_64 hardware supports VAAPI, you can switch to the direct renderer using the HUDIY_RENDERER environment variable.

Ring buffer optimizations

We also introduced optimizations to the ring buffer implementation. As a result, processing the projection data (video and audio) can be up to 12% faster, depending on the platform (L2 cache capacity) and resolution. This results in lower latency and reduced CPU and RAM usage.

---------------------------

You can download and install the update using the updater program – https://github.com/wiboma/hudiy/blob/ma ... d#updating

Please note that the updater performs an incremental update (version by version) to avoid the OS corruption during the update process. If you are using an older version of Hudiy, you may need to run the updater multiple times. You can check your current version in Menu -> Hudiy -> Settings -> About.

A description of all new features and configuration options is available on our GitHub in the updated documentation – GitHub.

Wow.. I always looking forward for each month ends for updates. Keep up the excellent work HUDIY!!

This is huge improvment

Pi5 price has increased. So I plan to use my leftover pi4. May I know which hudiy version can be used for pi4?

For Pi4 you can use both 1.16 (Bookworm) and 2.12 (Trixie). If you don't have a specific reason to use Bookworm (e. g. older version of the kernel), we recommend Trixie as it's the current OS version actively maintained by the Raspberry Pi Foundation. Trixie also supports Bluetooth cover art and 80MHz channel width in WiFi hotspots.

I use the latest installer and then I perform update. It straight away update to 2.12 for Trixie. How to do version to version update?

Due to the release of the direct renderer, the version currently being installed is 1.16/2.12 (1.x - Bookworm, 2.x - Trixie). If you are installing Hudiy after the 1.16/2.12 release, the installer will automatically install this version (which is currently the latest).

A version-by-version update is only required if your current Hudiy version is several versions behind, like 2.4. In that case (2.4), with each updater launch, the updater will incrementally update the software as follows:

2.4 -> 2.6
2.6 -> 2.8
2.8 -> 2.10
2.10 -> 2.12

It works this way to prevent any potential corruption to your operating system or your Hudiy installation.

Finally I got the 2.12 running. I have been using bookworm for 1.2 version. When running 2.12, there flashes of desktop screens. Is this given? Also it took longer to boot Trixie?

We didn't observe any differences between Bookworm and Trixie boot times. Regarding the desktop screen appearing during Hudiy startup, you can check:
